Detailed Description

Convert between undistorted focal plane and ground coordinates.

This base class is used to convert between undistorted focal plane coordinates (x/y) in millimeters and ground coordinates lat/lon. This class handles the case of framing cameras.

◆ LookDirection()

void Isis::VimsSkyMap::LookDirection ( double v[3])
private

Determines the look direction in the camera coordinate system.

Parameters
[out]vLook direction vector in camera coordinates

This method will compute the look direction vector in the camera coordinate system. This code was converted from Rick McCloskey's point_tbl c code.

History

2008-01-03 Tracie Sucharski - Converted Rick'scode rather than using the unitVector files from Rick.

2013-11-18 Tracie Sucharski - Added this method to VimsSkyMap,so that old unitVector files are no longer needed.

uydistorted focal plane y in millimeters
uzdistorted focal plane z in millimeters
Returns
conversion was successful
